FIELD: physics, optics.
SUBSTANCE: invention relates to methods and devices for forming an indicator for radial alignment of an intraocular lens relative to the eye. The method includes collecting preoperative angular alignment data relative to the pupil of an eye which is not dilated. The method also includes locating the pupil centre of the eye while dilated. The method further includes displaying the axis of angular alignment for a toric intraocular lens during operation on an image of the dilated eye relative to the centre of the dilated pupil based on the preoperative angular alignment data. The system is configured to implement the method and includes a computer-readable medium which stores a program executed by a processor to carry out steps of the method.
EFFECT: aligning an intraocular lens relative to the eye.
